57 / 148 page  DocID023353 Rev 13 57/148 STM32F303xB STM32F303xC Electrical characteristics 124 6.1.7 Current consumption measurement Figure 12. Current consumption measurement scheme 6.2 Absolute maximum ratings Stresses above the absolute maximum ratings listed in Table 21: Voltage characteristics, Table 22: Current characteristics, and Table 23: Thermal characteristics may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these conditions is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability. Table 21. Voltage characteristics(1) Symbol Ratings Min Max Unit VDD–VSS External main supply voltage (including VDDA, VBAT and VDD) -0.3 4.0 V VDD–VDDA Allowed voltage difference for VDD > VDDA -0.4 VREF+–VDDA(2) Allowed voltage difference for VREF+ > VDDA -0.4 VIN(3) Input voltage on FT and FTf pins VSS −0.3 VDD + 4.0 Input voltage on TTa pins VSS −0.3 4.0 Input voltage on any other pin VSS −0.3 4.0 Input voltage on Boot0 pin 0 9 | ΔVDDx| Variations between different VDD power pins - 50 mV |VSSX −VSS| Variations between all the different ground pins(4) -50 VESD(HBM) Electrostatic discharge voltage (human body model) see Section 6.3.12: Electrical sensitivity characteristics - 1. All main power (VDD, VDDA) and ground (VSS, VSSA) pins must always be connected to the external power supply, in the permitted range. The following relationship must be respected between VDDA and VDD: VDDA must power on before or at the same time as VDD in the power up sequence. VDDA must be greater than or equal to VDD. |
